The academic book "Sound Projection in Time" by Marcos Mesquita offers an in-depth musicological analysis that addresses sound projection as a temporal phenomenon. The dissertation presents five fundamental strategies that serve as a categorical framework for understanding music as an art of time. These strategies are not limited to the music of Helmut Lachenmann or the second half of the 20th century but have universal validity for all music. Furthermore, this work also discusses the prehistory of the phenomenon as well as significant musical considerations after 1950, which take on the character of a music philosophical text. Notably, the precise analysis of Lachenmann's orchestral work "Dust" is highlighted, which is conducted through a detailed examination of primary sources and the expansion of analytical criteria to include various aspects. This book is thus a valuable resource for anyone wishing to engage deeply with the theory and philosophy of music.
